• velocity

• size

• motion

If you know the distance an object has traveled in a certain amount of time, you can determine the

• size of the object

• speed of the object

• location of the object

• acceleration of the object

When you know both the speed and direction of an object's motion, you know the

• average speed of the object

• acceleration of the object

• distance the object has traveled

• velocity of the object

The steepness of a line on a graph is called the

• rise

• run

• slope/unit rate

• vertical axis

Average speed is

• equivalent to velocity

• the rate at which an object is moving at a given instant

• the rate at which a slope changes

• the total distance traveled divided by the total time

A place or object used for comparison to determine if something is in motion is called

• a position

• a reference point

• a constant

• velocity

The rate at which an object is moving at a given instant in time is know as

• speed

• instantaneous speed

• average speed

• fast speed

If an object moves in the same direction and at a constant speed for 4 hours, which of the following is true?

• the object's speed changed during the 4 hours

• the object's velocity did not change

• the object accelerated during the 4 hours

• the object decelerated during the 4 hours

When an object's distance from another object is changing,

• it is in motion.

• it is speeding.

• it has a high velocity.

• it is accelerating.

If distance is measured in kilometers and time is measured in hours, the unit of speed will be

• miles per hour

• kilometers per hour

• kilometers per hour per hour

• kilometers
